Foster Farms says it met demands by the U.S. Department of Agriculture by performing a thorough cleanup and treatment of its plant in Livingston, about 25 miles southeast of Modesto. The company says employees will be called back to work Saturday.

The plant closed Jan. 8 when inspectors found the cockroaches on five separate occasions in various parts of the plant over four months. The closure came three months after inspectors threatened a shutdown because of salmonella problems at the Livingston plant and two Foster Farms sites in Fresno.
